A body weighs 300 N on the surface of the earth. How much will it weigh at a distance R/2 below the surface of earth? ( R → Radius of earth) (a) 300 N (b) 250 N (c) 200 N (d) 150 N

Answer: (d). Wd = W(1 - d/R) with d = R/2. Wd = 300 × 1/2 = 150 N So the answer is (d) 150 N.

Acceleration Due to Gravity

A body weighs $300\text{ N}$ on the surface of the earth. How much will it weigh at a distance $\frac{R}{2}$ below the surface of earth? ( $R \rightarrow$ Radius of earth)

Show answer and solution

Answer: (d)

$W_d = W\left(1 - \frac{d}{R}\right)$ with $d = \frac{R}{2}$ .
$W_d = 300 \times \frac{1}{2} = 150\ \text{N}$
So the answer is (d) $150\ \text{N}$ .
